4 Claims.

The present invention embodies improvements in the art of Weatherstrippingand includes primarily novel construction of Weatherstrip devices designed for French windows which are of the iii-swinging casement type.

One of the objections heretofore incident to the useof swinging ,casement windows has resided in the diificulty of adequately Weatherstripping such windows,especially for the prevention oftlie entrance pf water. This invention, by the constructibnofthe appliances employed, facilitates the rendering of the window both air and {water-tight, under practical conditions of use.

Thefpre'sentimprovements comprise a special formation 'of rain-drip means for application to the outer lower portion of the casement window, and a special form of. hook Weatherstrip carried by the same portion of the window beneath the rain-drip member forcooperation with the inwardly extending lipor flange of a weatherstrip'channel that is located" on the sill below the lower edge io f the window when it is closed.

[One of the objects vof thelinvention resides in the provision of means upon the hook weatheristrip member acting as a gauge to assist in propjerlylocating the raindrip member for its proper attachment to the window so as to ensure a desired and necessary amount of clearance between -the ,rain-drip member and the s0-called channelj weatherstrip on the sill.

I @nhotherobjectof the invention is the cooperativeformation o the rain-drip. member and the hook 'weatherstrip j previously referred to, such that anfeiiect ive bracing action of the inner lower portion of the rain-drip is obtained by perculiar interengagement between said portion and fan attachment flange by which the hook weatherstripissecured 'in jplace onthe window.

fStill' another pbjectof theinvention is to so ,form the hook. Weatherstrip as to provide an at- -.tachment flange of relatively large area having a corresponding area of engagement with the fouter side of the window, so that any tendency of -the hookweatherstrip to buckle when secured to the window by its proper fastenings is obviated; Furthermore, the said attachment flange of the hook eatherstrip, by reason of its angular disposition to the hook member thereof andbysreason of. the size of the flange, aifords the advantage, of holding thehook member properly squared against the portion of the Window -oniwhich it fits. andito which it is secured byathe suitable fas'tenings employed. wilWith.athe1.above.'and other objects. in. view as will more fully appear hereinafter, certain preferred adaptations of my invention are illustrated in the accompanying drawing, in which- Figure 1 is a fragmentary sectional view of a window frame showing the lower portion of an 5 in-swinging casement type of window mounted therein as when closed, and illustrating the Weatherstrip means of the invention.

Figure 2 is a fragmentary view in perspective 7 showing more clearly the manner of mounting the rain-drip member and the hook Weatherstrip member coacting therewith in proper relation upon the lower portion wedge of the window or sash.

Figure 3 is a view somewhat similar to Figure 1 but illustrating a modified formation of the hook Weatherstrip and mode of coaction of the rain-drip member therewith; this view also illustrates a different type of channel 'weatherstrip member such as maybe useful to employ 2 in conjunction with my Weatherstrip improvements hereinafter to be set forth in detail.

Figure 4 is a sectional view of another modification.

Similar reference characters refer to parts throughout the drawing.

This application is a continuation in part of my previous application for patent, Serial No. 708,681, filed January 27, 1934. d

I shall first refer to Figures 1 and 2 of the drawing, which illustrate one adaptation or modification of my invention, and which constitute construction divided outrof the application for patent previously identified. In these figures the main sill of the window frame is indicated at I, and a stool 2 is shown adjacent thereto as a part of the frame construction in which the casement window or sash 3 is mounted. The mounting means for the sash 3 is not material to the invention, the type of sash shown beingknown as an 0 in-swinging casement window sash. In the angle between the main sill I and the stool 2 of the window frame there will be seen to be mounted what may be termed a Weatherstrip channel 4, the 45 base of which rests upon the sill I and is attached thereto by a fastening 5. The channel comprises the inner vertical iiange 6 which is in line with the outer side of. the structure 2 and having an inner face which is aligned with the i inner face or surface of the sash 3 when the sash is closed. The channel 4 additionally comprises the outer flange 1 having the weepholes 8 near its lower portion for the passag outwardly any water which may be trapped in the channel, '55

similar hook member II is bent downwardly and refolded upon itself, as shown at Ila, to provide a reinforced edge portion, the upper side of which is in the plane of the upper face of the lower side of said hook I I and has free sliding engagement with the lip or flange 9, as seen in Figure 1. In the formation of the refolded portion I Ia of the hook member ID it is notable that the lower member of the hook I I is deflected or bent downwardly at an angle. The bend that permits the edge portion to lie with its upper surface in the plane of the upper surface of the lower part of the hook provides a longitudinal reinforcing rib so to speak, and this formation adds substantially to the rigidity of the hook flange. Moreover, since the metal of the hook I I and member ID is very thin, if the edge of the part IIa were free and not countersunk as provided by me, the tendency of said edge would be to grab or engage the metal of the part 9, causing sticking and interfering with the ease of operation of the device. Again,

,Where the refolded portion is not flush or countersunk as described, there is formed a dirt catching groove inwards of the projecting edge and such groove tends to hold dirt and foreign matter to an extent that reduces the efliciency of the sealing action of the hook, as will be self-evidentto those versed in this art. In my construction no lodgment of dirt or foreign matter will ensue in the use of the Weatherstrip because the upper surface of the lower member of the hook I I is substantially continuous and the efiiciency of my seal for Weatherstrip purposes is maintained under all conditions of service.

Projecting upwardly from the hook member I 0 is an attachment flange I2, and I purposely make this flange of relatively large area so as to provide a relatively large vertical member extending upwardly at substantially a right angle to the hook Ill. The area of this member I2 is such that it reduces the liability of buckling of the same when the fastening means consisting of the nails or screws I3 are applied to the window to attach the part I2 thereto. Likewise, the formation of the parts I0 and I2 and their relative sizes provides a considerable area for the angular section therebetween, facilitating the squaring of the -hook member in proper relation to the recessed portion I4 of the lower edge of the window in which the hook proper is seated.

Above and at the outer side of the flange I2 of the hook member I8 is disposed the rain-drip member I5 which consists of an overhanging body,

an attachment flange I6 secured by nails or other fastenings I! to the sash 3, and an underhung I or bracing flange I8 which projects inwardly from the overhanging body of the rain-drip member I5. In general form this rain-drip member I5 -isknown in the art, but its relative mounting and cooperation with the portion I2 of the hook member ID is a novel feature of the invention. Describing this feature more fully, it is notable that the flange I2 is formed longitudinally thereof with a pressed-out rib or bead I9. This rib or bead I9 is located especially with a View to 00- operation thereof with the underhung flange I8 of the rain-drip member I5. In other words the inner edge of the flange I8 of the member I5, according to Figures 1 and 2, is designed to contact with the bead or rib I9 just above the same, and when so engaged, after the hook member III has been secured in position by its nails or fastenings I3, the rain-drip member I5 will be properly positioned so as to afford ample clearance between its lowermost portion and the uppermost portion of the channel 4, which uppermost portion is, of course, the flange or lip 9.

It is contemplated that the installer of my Weatherstrip means, as herein described, will always first position the rain-drip member I5 so that it is mounted in relation to the bead or rib I9 as shown in Figures 1 and 2, and thereafter the fastenings Il may be driven in place to attach the member I5 to the sash 3, and the proper clearance previously referred to as regards the parts 9 and I5 will be established.

Now I have illustrated in Figure 3 of the drawing a modified adaptation of my invention wherein the parts that correspond with the parts shown in Figure 1 are similarly numbered. The primary differences in the construction of Figure 3 from that of Figure 1 reside in the formation of the channel member, which is something not material to the invention because different kinds of channel members may be availed of for the purposes of the invention. However, in the Figure 3 construction, the bead or rib I9 is located a little higher on the flange I2 than is the arrangement of said bead as illustrated in Figures 1 and 2. This calls for a cooperative disposition of the parts I5 and I2 such that the inner edge of the flange I8 will be installed in contact with the part I2 just below the shoulder which is provided by the bead or rib I9. Under these conditions it will be apparent from Figure 3 that the member IS in its coaction with the part I8 of the rain-drip member I5 has a sort of interlocking relation such that a bracing effect between these parts is obtained. In other words,

any tendency, by accidental pressure, or the impingement of a blow against the outer side of the member I5, to force said member inwardly or flatten it against the window sash 3, is prevented because the part I8 has the said interlocking located above the same to thereby prevent move-.

ment of member I8 in vertical direction.

When a plurality of ribs or beads is employed the same may preferably be formed, as shown in Figure 4, wherein both beads are of a V-like configuration as clearly shown at 20. Adjacent ends of the V-like beads form a V-like recess 2 I, which extends longitudinally over the entire length of the attachment flange of the hook member II. In this manner the flange I8 of the rain-drip member I5 may be held against displacement in an upward as well as in a downward direction.

The upper end 22 of the attachment flange I2 is slightly bent, as shown in Figure 4, for engaging the rain-drip member I5, and a better positioning and securing of members I2 and I5, with respect to each other and the sash, may be thereby facilitated.

It will be apparent that in regard to the adaptations of the invention illustrated herein the proper locating of the rain-drip member in relawater-tight and weather-proof, and quite advantageous from the viewpoint of enabling the quick and proper installation and effective attachment of parts thereof to the window under practical conditions of installing work.

Having thus described my invention, what I claim as new and desire to secure by Letters Pat- 7 cut of the United States, is-

1. In Weatherstrip construction for swinging casement windows, in combination, a window sash, a hook Weatherstrip member carried by said sash and provided with a guide or gauge part thereon, and a separate rain-drip member having a portion to cooperate with said guide or gauge part of the hook member to facilitate the proper positioning of the rain-drip member on the sash, and fastening means for connecting the raindrip member and the hook member to the sash.

2. In Weatherstrip construction for swinging casement windows, in combination, a hook member for the lower edge portion of. the sash, comprising a vertical flange extending at an angle thereto so that a lower corner portion of the sash may be received in the angle between said vertical flange and the hook member, means for securing the hook member to the sash, the said hook member adapted to coact with a Weatherstrip member below the sash and said flange being provided with a protuberant rib-like gauge or guide part extending longitudinally of the flange, a separate rain-drip member secured to the sash at the outer side of and above the flange of the hook member, said rain-drip member having a portion adapted to be aligned with the rib-like gauge or guide part aforesaid, whereby to facilitate the proper positioning of the rain-drip member relatively to the hook member to afford a proper clearance between the rain-drip member and the weatherstripmember with which the hook member cooperates.

3. In Weatherstrip construction for swinging casement windows, in combination, a sash, a hook member applied to a corner portion of the sash and having an offstanding flange for attachment thereof to the sash, fastening means connecting said flange to the sash to support the hook member properly upon the sash, the said flange being provided with an outwardly extending rib longitudinally thereof. and forming a gauge part, and a separate rain-drip member comprising a metal plate overhanging the flange of the hook member at the outer side thereof and attached to the sash, said plate being bent inwardly at its lower end to provide an underhung flange having the edge thereof engaged with the gauge part of the flange of the hook member so as to enable proper positioning of the raindrip member in relation to the hook member and a Weatherstrip part with which the hook member may cooperate.

4. In Weatherstrip construction for swinging casement windows, in combination, a sash, a hook member applied to a corner portion of the sash and having an offstanding flange for attachment thereof to the sash, fastening means connecting said flange to the sash to support the hook member properly upon the sash, the said flange being provided with an outwardly extending rib longitudinally thereof and forming a gauge part, and a separate rain-drip member comprising a metal plate overhanging the flange of the hook member at the outer side thereof. and attached to the sash, said plate being bent inwardly at its lower end to provide an underhung flange having the edge thereof engaged with the gauge part of the flange of the hook member so as to enable proper positioning of the rain-drip member in relation to the hook member and a Weatherstrip part with which the hook member may cooperate, the underhung flange of the rain-drip member inclining upwardly and being disposed in interlocking engagement with and below the gauge part of the attachment flange of the hook member, whereby such interlocking engagement with the underhung flange of the rain-drip member affords a bracing action against pressure inwardly on the rain-drip member in the direction of the sash.
